What was the real HP on the 2011 5.0?
The Motor came rated at 412..
They were being conservative and also cautious because FORD overstated an earlier HP number with a Shelby model that came back to haunt them.
Don't remember the details of that but do remember it was a PR snafu they were cautious to not repeat and thus "under" reported the first year of the 5.0 at 412.
Seems to be no other good reason a manufacturer would use 412... Round it up or down..
Any thoughts on this?

from a MT article back in 2010...
"A run on the dyno at K&N Air Filters in Riverside, CA, suggests actual output to be around 435 horsepower and 404 pound-feet"

When you consider the drivetrain loss (est. 15%) and that most stock 5.0's seem to put down approx. 370-380 RWHP then 435-440 FWHP sounds accurate.
We won't know for sure until someone actually puts a stock engine on an engine dyno.

That was it, thanks for bringing it to remembrance. Cobra not a Shelby. Didn't Ford bring vehicles back in and mod them to meet the number claimed? I could look it up but I think that happened.
The bottom line on the 412 number is it's low and an odd sounding number to publish.. When people ask a number on my car I say 420/400.

It's widely believed that the Mustang version of the 5.0 is about 430-435 crank-hp and it has been there since day one, with the 2011's and on.
Yes, under-rated like the 03-04 Cobras, although not as much.
As far as the 412 number being a strange number, that can simply be a random number Ford choose to make the public believe that they've gotten all they could out of that engine.
Chevy does it with the manual-trans Camaro at 426 hp, the Lumina's optional V8 had 303hp and many other engines have and had odd ratings like that ...
